Definitions
- Embodiments of the present invention relate to a wafer level package with integrated antenna as well as to a respective manufacturing method.
- Preferred embodiments relate to a miniaturized fan-out panel/wafer level-based system integration platform with integrated antenna.
- the antennas in eWLB and InFO cannot be optimized without adapting the dimensions of the RDL and the mold material, which limits the freedom of design of the platform.
- a wafer level package with integrated antenna may have: a contacting layer; an antenna layer with the integrated antenna; and a chip layer including at least one chip arranged between the contacting layer and the antenna layer, wherein means for shielding are implemented between the antenna layer and the chip layer.
- Another embodiment may have a system including the inventive wafer level package, wherein a further wafer level package is connected to the wafer level package via the contacting layer.
- Embodiments of the present invention provide a wafer level package with integrated antenna.
- the wafer level package comprises a contacting layer, an antenna layer with integrated antenna as well as a chip layer arranged between the contacting layer and the antenna layer including at least one chip.
- Means for shielding such as a shielding plane or generally a shield are provided between the antenna layer and the chip layer.
- a redistribution layer can be implemented between the means for shielding and the chip layer.
- Embodiments of the present invention are based on the knowledge that it is advantageous in a layered structure of antenna part and chip part when shielding is provided between these two layers, which protects both the chips/ICs of the chip layer from the radiation of the antenna and vice versa shields the antenna from EMC influences of the chips.
- the arrangement of the redistribution plane on the side of the shield facing away from the antenna is advantageous since in that way mutual interferences can be prevented by the shield. Additionally, it should be mentioned that decoupling of chip layer and antenna layer allows enables a relatively flexible design of both planes, since now hardly any or only few interactions have to be considered.
- the chip plane is formed by one or several chips in combination with a mold material.
- connection between the redistribution plane and the contacting plane can be established, for example by vias.
- chips are contacted on both sides, i.e., via the redistribution plane and via the contacting plane.
- means for temperature dissipation for the chip can be provided. In that way, there is not only the advantageous possibility of designing both chip plane and antenna layer in a flexible manner, but also a maximum degree of freedom and the provision of further elements, such as the cooling elements, respectively, is enabled for the contacting plane.
- a dielectric can be provided between the antenna layer and the means for shielding.
- this dielectric can also be perforated in order to allow filter functionality.
- the antenna plane can also include a plurality of antenna elements.
- an isolation layer can be provided between the chip plane and the above discussed redistribution plane.
- contacting is established, for example, by means of a via projecting through the means for shielding and possibly existing further layers (dielectricity layer and isolation layer).
- this via connects the chip, such as the RF chip of the chip plane to one or several antenna elements.
- the one or several antennas can be contacted by means of electromagnetic coupling.
- the antenna layer can be deposited, for example, by means of laminating, planar adhesion or via a glass substrate.
- FIG. 1 is a schematic illustration of a wafer level package with integrated antenna according to a basic embodiment
- FIG. 2 a -2 d are schematic sectional views of wafer level packages with integrated antenna according to extended embodiments
- FIG. 2 e is a schematic sectional view of a wafer level package with lens according to an embodiment
- FIG. 2 f is a schematic sectional view of a wafer level package with housing according to an embodiment
- FIGS. 3 a and 3 b are schematic illustrations of wafer level packages according to conventional approaches.
- the means for shielding are formed by a shielding layer 16 , i.e., for example, by a metallization plane.
- the chip 12 a is connected, for example, via this redistribution plane in the layer and/or via the contacting layer 18 .
- the redistribution plane of the layer 20 can be connected to the contacting layer 18 , e.g., by means of vias.
- a via can also extend from the chip 12 a to the integrated antenna 14 a in order to contact the same.
- the structure described herein offers advantages with respect to complete integration of the antennas 14 a , chips 12 a , passive components and other system components into the fan-out panel/wafer level-based system integration platform and module 10 , respectively.
- the functionality of the platform and the module 10 is completely independent from the printed circuit board.
- FO-WLP such as eWLB
- the reflector of the antennas is integrated on the printed circuit board.
- the functionality of the antennas and also of the platform and the module, respectively depends on the dimensions of the BGA balls, the process variations and also on the printed circuit board.
- these antennas 14 a can be optimized without changing the residual structure of the platform and the module 10 , respectively. In other FO-WLP modules, this is not the case, for optimizing antennas 14 a in eWLB and InFO, for example, the dimensions of the RDL mode material have to be adapted.
- the fields of the integrated antennas 14 a are completely shielded from the chips 12 a , passive and other components that are integrated in the fan-out panel/wafer level-based system integration platform and module, respectively. Thereby, EMC problems are prevented. In other fan-out modules, this is not the case. Neither in InFo-WLP nor in eWLB are the antennas 14 a shielded from the chips 12 a.
- FIG. 2 a shows a wafer level package 10 ′ with the chip layer 12 ′, the antenna layer 14 ′, wherein the shielding layers 16 as well as the redistribution plane 20 ′, respectively, are provided between the chip layer 12 ′ and the antenna layer 14 ′. Additionally, the contacting plane 18 is arranged on the bottom side of the chip layer 12 ′.
- the chip layer 12 ′ includes the two chips 12 a and 12 b that are integrated in a so-called fan-out area 12 f including other ICs, passive or other systems components.
- This fan-out area 12 f is typically formed by a polymer and mold material, respectively.
- the antenna 14 a ′ extends across the entire antenna layer 16 and here in particular across the surface of the same.
- the antenna layer 14 is, for example, formed by a glass substrate, a polymer, a laminate etc., which forms the respective dielectric 14 ′ for the antenna 14 a .
- the individual antenna areas and antenna planes are completely embedded into the dielectric 14 d′.
- the antenna 14 a is connected to the chip 12 a ′, here a RF chip by means of a vertical via.
- via 16 f ′ represents the shortest connection. This short signal path with few discontinuities allows the signal integrity, also for millimeter waves and terahertz signals.
- electromagnetic coupling e.g., via aperture coupling or near field coupling can be realized to the vertical probe 16 f ′.
- a planar connector such as a transmission line is used.
- the layer 20 ′ includes the redistribution plane 20 u ′, e.g., for signal distribution and current supply as well as the isolator 20 i ′ arranged between the chip plane 12 ′ and the redistribution plane 20 ′.
- the redistribution plane 20 ′ consists of one or several metal and dielectric isolation layers.
- passive components such as inductances, resistors, capacitors, filters or other elements can be integrated in the redistribution plane 20 ′ and in particular in the metallization plane 20 u ′. Alternatively, embedding these passive elements into the mold material of the chip plane 12 ′ would be possible, wherein then these passive elements are contacted via the redistribution plane 12 u′.
- the antenna substrate 16 + 14 ′ consisting of at least two metal layers 16 and 14 a ′ (means for shielding and antenna) as well as one dielectric layer 14 d ′ arranged there between lies above the redistribution plane 20 u ′.
- the metal layer 16 serves to shield the antenna fields from the integrated components.
- the antenna 14 a ′ can be built of either of one or several radiating elements (antenna array) and, as mentioned above, the same is excited either galvanically with the help of a conductor or a via (probe feed) or electromagnetic coupling (e.g., aperture coupled, proximity feed).
- the electronics e.g., circuits and/or diodes usually necessitated for re-configurability can either be integrated in the antenna substrate 16 + 14 ′, in the redistribution plane 20 ′, the polymer substrate 12 ′ (i.e., together with the ICs 12 a and 12 b ).
- the electronics for controlling the antenna e.g., phase shifter
- the electronics for controlling the antenna is arranged either in the redistribution plane 20 ′ or in the chip plane 12 ′, respectively.
- the antenna can radiate out of the surface plane, can radiate to the side (azimuth plane) or in both directions, depending on the antenna configuration. As illustrated, in the embodiment presented herein, radiation is performed in particular out of the main surface of the antenna 14 a′.
- the platform and the module 10 ′ respectively, allows the radiation of the integrated antennas 16 a ′ into the entire hemisphere (i.e., in the entire azimuthal and vertical plane) without causing undesired coupling with other integrated components. This is possible because no other components are integrated on the antenna plane 14 ′. With eWLB, e.g., this is not the case, since the ICs 12 a , 12 b and other components are integrated on the same plane as the antennas 14 a ′. When it has been assumed in the above embodiments 10 and 10 ′ that radiation of the antenna 14 a ′ takes place only out of the main surface, such as illustrated in FIG. 2 d , radiation can also take place to the side.
- the wafer level package of FIG. 2 d is provided with reference number 10 ′′ and will be discussed in detail with reference to FIG. 2 d.
- FIG. 2 b shows a modified embodiment of the wafer level package 10 ′, namely the wafer level package 10 ′′. This differs from the wafer level package 10 ′ with respect to the antenna substrate in the antenna layer 14 ′′.
- the antenna substrate includes the elements antenna 14 a ′, dielectric 14 d ′ as well as means for shielding 16 .
- the antenna substrate and in particular the dielectric 14 d ′′ can include a polymer material, a glass material, a RF laminate or another suitable RF material.
- the dielectric layer 14 d ′′ is provided with periodic holes, i.e., the same is perforated.
- the substrate 14 + 16 behaves like a photonic band gap structure resulting in filtering the surface waves and hence improving the radiation characteristic. Further, the value of the effective monivity of the substrate is decreased due to the holes. Thereby, the edge length of the antenna structure is increased at higher frequencies and the influence of process variations becomes lower.
- the radiation characteristic of the antenna 16 a ′ can also be improved by integrating electromagnetic band gap structures (EBG) either in the antenna substrate 14 ′′+ 16 or the redistribution plane 20 u′.
- ESG electromagnetic band gap structures
- FIG. 2 c shows a further modification starting from the wafer level package 10 ′, namely the wafer level package 10 ′′.
- the contacting plane 18 (now 18 ′) is implemented in a modified manner.
- the modification is selected such that in the area of the chip 12 a , instead of the contacts for connecting to the bottom side, contacting means for heat dissipation, here a cooling body 18 k ′, are provided in order to dissipate heat from the chip 12 a .
- the cooling body 18 k ′ spreads the heat into the environment below the chip 12 a and the solder balls 18 f transfer the heat into the next package level, i.e., the system board.
- a thermally conductive material can be provided between chip and cooling body 18 k ′.
- heat dissipation would also be possible via the above discussed solder balls 18 s , wherein then usually also a thermally conductive material is used.
- the surface of the chip 12 a is exposed.
- the chip rear side can be exposed directly in the mold process.
- subsequent grinding away would also be possible.
- the metallization typically necessitated in the cooling body 18 k ′ can either be provided in the chip 12 a already prior to packaging or can be deposited, e.g., via a thin film wiring layer or a sputtering layer with galvanic reinforcement.
- a further embodiment provides a respective manufacturing method.
- the chip substrate 12 ′ is provided together with the contacting plane 18 and 18 ′, respectively, as well as the optional redistribution plane 20 ′.
- This antenna layer 14 ′+ 16 can then be deposited, e.g., via laminating (RF substrate), layer by layer in thin film technology and by planar adhesion (glass).
- the antenna layer 14 a ′ can either be structured already prior to assembly or can also be structured sequentially after assembly. In other words, this means that the chip substrate 12 ′ with the redistribution plane 20 ′ is connected to the antenna substrate 14 ′+ 16 . This connection is performed on wafer level.
- FIG. 2 e shows the wafer level package 10 ′ of FIG. 2 a with chip layer 12 ′, antenna layer 14 ′, shielding layer 16 as well as redistribution plane 20 ′.
- the wafer level package 10 ′ has an additional lens 21 (means for beam forming the electromagnetic wave emitted by the antenna) on the top side (main surface) adjacent to the antenna 14 a ′. This lens 21 serves for vertical focusing of the antenna beam.
- FIG. 2 f shows again the wafer level package 10 ′ of FIG. 2 a in combination with a housing 23 disposed on the top side (side of the antenna 14 ′).

Abstract
Description
- This application claims priority from German Patent Application No. 10 2017 200 122.4, which was filed on Jan. 5, 2017, which is incorporated herein in its entirety by this reference thereto.
- Embodiments of the present invention relate to a wafer level package with integrated antenna as well as to a respective manufacturing method. Preferred embodiments relate to a miniaturized fan-out panel/wafer level-based system integration platform with integrated antenna.
- Embodiments of the present invention relate to a wafer level package with at least one integrated antenna element as well as to a respective manufacturing method. Preferred embodiments relate to a fan-out panel/wafer level-based system integration platform with superstrate integrated antennas without redistribution plane.
- The antennas in eWLB and InFO cannot be optimized without adapting the dimensions of the RDL and the mold material, which limits the freedom of design of the platform.
- Both in eWLB and in InFO, the fields of the integrated antennas are not shielded from the chips and other integrated components. The undesired interaction can result in EMC problems.
- In eWLB, the radiation of an integrated antenna cannot cover the entire hemisphere (the entire horizontal and vertical plane) without causing undesired coupling with other integrated components. The reason for that is that other components are integrated on the same plane as the antennas. Thus, there is the need for an improved approach.
- According to an embodiment, a wafer level package with integrated antenna may have: a contacting layer; an antenna layer with the integrated antenna; and a chip layer including at least one chip arranged between the contacting layer and the antenna layer, wherein means for shielding are implemented between the antenna layer and the chip layer.
- Another embodiment may have a system including the inventive wafer level package, wherein a further wafer level package is connected to the wafer level package via the contacting layer.
- According to another embodiment, a method of manufacturing a wafer level package with integrated antenna may have the steps of: arranging a contacting layer; arranging a chip layer including at least one chip on the contacting layer; arranging means for shielding on the chip layer; and arranging an antenna layer on the means for shielding.
- Embodiments of the present invention provide a wafer level package with integrated antenna. The wafer level package comprises a contacting layer, an antenna layer with integrated antenna as well as a chip layer arranged between the contacting layer and the antenna layer including at least one chip. Means for shielding, such as a shielding plane or generally a shield are provided between the antenna layer and the chip layer. According to embodiments, also, a redistribution layer can be implemented between the means for shielding and the chip layer.
- Embodiments of the present invention are based on the knowledge that it is advantageous in a layered structure of antenna part and chip part when shielding is provided between these two layers, which protects both the chips/ICs of the chip layer from the radiation of the antenna and vice versa shields the antenna from EMC influences of the chips. The arrangement of the redistribution plane on the side of the shield facing away from the antenna is advantageous since in that way mutual interferences can be prevented by the shield. Additionally, it should be mentioned that decoupling of chip layer and antenna layer allows enables a relatively flexible design of both planes, since now hardly any or only few interactions have to be considered.
- According to embodiments, the chip plane is formed by one or several chips in combination with a mold material. When it is assumed that the redistribution plane is on the side of the side facing the antenna, according to embodiments, connection between the redistribution plane and the contacting plane can be established, for example by vias. Alternatively or additionally, it would also be possible that chips are contacted on both sides, i.e., via the redistribution plane and via the contacting plane. Instead of contacting the chips on the side of the contacting plane via this plane, also, means for temperature dissipation for the chip can be provided. In that way, there is not only the advantageous possibility of designing both chip plane and antenna layer in a flexible manner, but also a maximum degree of freedom and the provision of further elements, such as the cooling elements, respectively, is enabled for the contacting plane.
- According to the following embodiments, a dielectric can be provided between the antenna layer and the means for shielding. According to additional embodiments, this dielectric can also be perforated in order to allow filter functionality. In this concept, it is advantageous that both the material and the thickness of the dielectricity layer can be varied without influencing the other layers. Here, it should also be noted that, according to embodiments, the antenna plane can also include a plurality of antenna elements. Analogously to the dielectric, an isolation layer can be provided between the chip plane and the above discussed redistribution plane. According to again further embodiments, contacting is established, for example, by means of a via projecting through the means for shielding and possibly existing further layers (dielectricity layer and isolation layer). Thus, this via connects the chip, such as the RF chip of the chip plane to one or several antenna elements. Alternatively, according to further embodiments, the one or several antennas can be contacted by means of electromagnetic coupling.
- Further embodiments provide a method of manufacturing a wafer level package with integrated antenna. In this method, first, the contacting layer is manufactured together with a chip layer before the antenna layer is arranged on the chip layer with means for shielding arranged in between.
- The antenna layer can be deposited, for example, by means of laminating, planar adhesion or via a glass substrate.

-
FIG. 1 shows awafer level package 10 with achip layer 12, anantenna layer 14 as well as means for shielding (cf. reference number 16) that are arranged between thechip layer 12 and theantenna layer 14. Additionally, thewafer level package 10 comprises a contactinglayer 18 which is arranged on the bottom side of thechip layer 12, i.e., on the side of thechip layer 12 opposite to theantenna layer 14. - The
antenna layer 14 includes at least one integrated antenna or an antenna array, here the integratedantenna 14 a and advantageously, but not necessarily adielectric area 14 d which is normally arranged between theantenna 14 a and thelayer 16 with means for shielding. - In this embodiment, the means for shielding are formed by a
shielding layer 16, i.e., for example, by a metallization plane. - The
chip layer 12 includes one or several chips, here thechip 12 a (such as a RF chip) which is embedded in thelayer 12. Embedding can be performed, for example, by means of a fan-out panel/wafer level process with the help of polymer, such as a mold material. According to embodiments, afurther layer 20 can be provided between theshielding layer 16 and thechip layer 12, which includes, e.g., a redistribution plane and/or isolation layers. - The
chip 12 a is connected, for example, via this redistribution plane in the layer and/or via the contactinglayer 18. According to embodiments, the redistribution plane of thelayer 20 can be connected to the contactinglayer 18, e.g., by means of vias. According to further embodiments, a via can also extend from thechip 12 a to the integratedantenna 14 a in order to contact the same. - The structure described herein offers advantages with respect to complete integration of the
antennas 14 a,chips 12 a, passive components and other system components into the fan-out panel/wafer level-based system integration platform andmodule 10, respectively. Thereby, the functionality of the platform and themodule 10, respectively, is completely independent from the printed circuit board. In other state of the art FO-WLP, such as eWLB, this is not the case. Here, the reflector of the antennas is integrated on the printed circuit board. Thereby, the functionality of the antennas and also of the platform and the module, respectively, depends on the dimensions of the BGA balls, the process variations and also on the printed circuit board. - Since optionally a
separate substrate 14 is used forintegrated antennas 14 a, theseantennas 14 a can be optimized without changing the residual structure of the platform and themodule 10, respectively. In other FO-WLP modules, this is not the case, for optimizingantennas 14 a in eWLB and InFO, for example, the dimensions of the RDL mode material have to be adapted. - The fields of the
integrated antennas 14 a are completely shielded from thechips 12 a, passive and other components that are integrated in the fan-out panel/wafer level-based system integration platform and module, respectively. Thereby, EMC problems are prevented. In other fan-out modules, this is not the case. Neither in InFo-WLP nor in eWLB are theantennas 14 a shielded from thechips 12 a. - With reference to
FIGS. 2a-2f , extended embodiments will be explained. -
FIG. 2a shows awafer level package 10′ with thechip layer 12′, theantenna layer 14′, wherein the shielding layers 16 as well as theredistribution plane 20′, respectively, are provided between thechip layer 12′ and theantenna layer 14′. Additionally, the contactingplane 18 is arranged on the bottom side of thechip layer 12′. - The
chip layer 12′ includes the twochips area 12 f including other ICs, passive or other systems components. This fan-outarea 12 f is typically formed by a polymer and mold material, respectively. - The
antenna 14 a′ extends across theentire antenna layer 16 and here in particular across the surface of the same. Theantenna layer 14 is, for example, formed by a glass substrate, a polymer, a laminate etc., which forms therespective dielectric 14′ for theantenna 14 a. As can be seen, the individual antenna areas and antenna planes are completely embedded into the dielectric 14 d′. - For contacting the
antenna 14 a′, theantenna 14 a is connected to thechip 12 a′, here a RF chip by means of a vertical via. As the illustration shows, via 16 f′ represents the shortest connection. This short signal path with few discontinuities allows the signal integrity, also for millimeter waves and terahertz signals. Alternatively, also, electromagnetic coupling, e.g., via aperture coupling or near field coupling can be realized to the vertical probe 16 f′. Further, it would also be possible that in addition to the vertical vias 16 f′ a planar connector, such as a transmission line is used. - The
layer 20′ includes theredistribution plane 20 u′, e.g., for signal distribution and current supply as well as the isolator 20 i′ arranged between thechip plane 12′ and theredistribution plane 20′. According to further embodiments, theredistribution plane 20′ consists of one or several metal and dielectric isolation layers. Additionally, passive components, such as inductances, resistors, capacitors, filters or other elements can be integrated in theredistribution plane 20′ and in particular in themetallization plane 20 u′. Alternatively, embedding these passive elements into the mold material of thechip plane 12′ would be possible, wherein then these passive elements are contacted via the redistribution plane 12 u′. - On the front, the
ICs redistribution plane 20 u′ viapads 20 p′. Further, theredistribution plane 20 u′ contacts the contactinglayer 18 by means ofvias 12 v′ that project through themold material 12 f and generally through thechip plane 12′. By means of the electrically conductive via 12 v′ through the embedded polymer (mold compound) 12 f, the redistribution layers 20 u′ including theantenna layer 14 a′ can be routed to the packagerear side 18 for contacting the substrate. This contactinglayer 18 includes, for example, solder balls and thermal balls, respectively, via which theentire package 10′ is contacted. In this embodiment, it is also the case that thesolder balls 18 s and the contacting elements of the contactinglayer 18, respectively, are provided on the bottom side of theICs ICs - The antenna substrate 16+14′ consisting of at least two
metal layers dielectric layer 14 d′ arranged there between lies above theredistribution plane 20 u′. As already mentioned above, themetal layer 16 serves to shield the antenna fields from the integrated components. Theantenna 14 a′ can be built of either of one or several radiating elements (antenna array) and, as mentioned above, the same is excited either galvanically with the help of a conductor or a via (probe feed) or electromagnetic coupling (e.g., aperture coupled, proximity feed). Depending on the desired radiation characteristic, the antenna substrate 16+14′ allows the realization of different antenna configurations, e.g., patch, grid array, slit, substrate integrated wave guide (SIW) based antennas, dipole, monopole, Yagi-Uda, Vivaldi, etc. According to further embodiments, the integrated antennas can also be configured in an “intelligent” manner, i.e., reconfigurable, controllable, adaptive and smart, respectively. The electronics (e.g., circuits and/or diodes) usually necessitated for re-configurability can either be integrated in the antenna substrate 16+14′, in theredistribution plane 20′, thepolymer substrate 12′ (i.e., together with theICs redistribution plane 20′ or in thechip plane 12′, respectively. - Starting from the structure of the
wafer level package 10′ presented herein, the antenna can radiate out of the surface plane, can radiate to the side (azimuth plane) or in both directions, depending on the antenna configuration. As illustrated, in the embodiment presented herein, radiation is performed in particular out of the main surface of theantenna 14 a′. - The platform and the
module 10′, respectively, allows the radiation of the integrated antennas 16 a′ into the entire hemisphere (i.e., in the entire azimuthal and vertical plane) without causing undesired coupling with other integrated components. This is possible because no other components are integrated on theantenna plane 14′. With eWLB, e.g., this is not the case, since theICs antennas 14 a′. When it has been assumed in theabove embodiments antenna 14 a′ takes place only out of the main surface, such as illustrated inFIG. 2d , radiation can also take place to the side. Here, it should be noted that the wafer level package ofFIG. 2d is provided withreference number 10″ and will be discussed in detail with reference toFIG. 2 d. -
FIG. 2b shows a modified embodiment of thewafer level package 10′, namely thewafer level package 10″. This differs from thewafer level package 10′ with respect to the antenna substrate in theantenna layer 14″. The antenna substrate includes theelements antenna 14 a′, dielectric 14 d′ as well as means for shielding 16. As already discussed above, the antenna substrate and in particular the dielectric 14 d″ can include a polymer material, a glass material, a RF laminate or another suitable RF material. In this embodiment, thedielectric layer 14 d″ is provided with periodic holes, i.e., the same is perforated. Thereby, the substrate 14+16 behaves like a photonic band gap structure resulting in filtering the surface waves and hence improving the radiation characteristic. Further, the value of the effective primitivity of the substrate is decreased due to the holes. Thereby, the edge length of the antenna structure is increased at higher frequencies and the influence of process variations becomes lower. The radiation characteristic of the antenna 16 a′ can also be improved by integrating electromagnetic band gap structures (EBG) either in theantenna substrate 14″+16 or theredistribution plane 20 u′. -
FIG. 2c shows a further modification starting from thewafer level package 10′, namely thewafer level package 10″. In the same, compared to thewafer level package 10′, the contacting plane 18 (now 18′) is implemented in a modified manner. The modification is selected such that in the area of thechip 12 a, instead of the contacts for connecting to the bottom side, contacting means for heat dissipation, here a coolingbody 18 k′, are provided in order to dissipate heat from thechip 12 a. The coolingbody 18 k′ spreads the heat into the environment below thechip 12 a and the solder balls 18 f transfer the heat into the next package level, i.e., the system board. - According to the embodiments, a thermally conductive material can be provided between chip and cooling
body 18 k′. Here, it should be noted that, according to further embodiments, heat dissipation would also be possible via the above discussedsolder balls 18 s, wherein then usually also a thermally conductive material is used. - From a manufacturing point of view, there are different options how the surface of the
chip 12 a is exposed. According to a first variation, the chip rear side can be exposed directly in the mold process. Alternatively, subsequent grinding away would also be possible. The metallization typically necessitated in the coolingbody 18 k′ can either be provided in thechip 12 a already prior to packaging or can be deposited, e.g., via a thin film wiring layer or a sputtering layer with galvanic reinforcement. - Even when the above embodiments have been discussed in the context of the apparatus, a further embodiment provides a respective manufacturing method. Here, in a first basic step, the
chip substrate 12′ is provided together with the contactingplane optional redistribution plane 20′. Thelayer 20′ and also after depositing thelayer 20′, theantenna substrate 14′+16 is deposited. Thisantenna layer 14′+16 can then be deposited, e.g., via laminating (RF substrate), layer by layer in thin film technology and by planar adhesion (glass). Here, theantenna layer 14 a′ can either be structured already prior to assembly or can also be structured sequentially after assembly. In other words, this means that thechip substrate 12′ with theredistribution plane 20′ is connected to theantenna substrate 14′+16. This connection is performed on wafer level. -
FIG. 2e shows thewafer level package 10′ ofFIG. 2a withchip layer 12′,antenna layer 14′, shieldinglayer 16 as well asredistribution plane 20′. In this embodiment, thewafer level package 10′ has an additional lens 21 (means for beam forming the electromagnetic wave emitted by the antenna) on the top side (main surface) adjacent to theantenna 14 a′. Thislens 21 serves for vertical focusing of the antenna beam. -
FIG. 2f shows again thewafer level package 10′ ofFIG. 2a in combination with ahousing 23 disposed on the top side (side of theantenna 14′). Thehousing 23 is made of glass or another non-shielding material. Thehousing 23 can, for example, be filled with air or a dielectric low-loss material. Further, thehousing 23 can also contribute to beam forming/focusing of the electromagnetic wave. Both thehousing 23 and thelens 21 can be applied together and in combination with all above-explained embodiments/wafer level package. - According to a further embodiment, a system is provided where the wafer level package is connected to (at least) one further (different or same) wafer level package. Connection is established, e.g., via the contacting layer. The further wafer level package can, for example, include also one or several antennas (array), such that a three-dimensional antenna structure is provided as a result.
- All above-stated embodiments, in particular the embodiments of
FIGS. 2a-2d , have in common that a short connectingpath 16 v′ without many geometric discontinuities is enabled from thefront end IC 12 a to theantenna 14 a′, which results in good signal integrity, e.g., in the millimeter wave range or terahertz range. The platform and themodule 10′, 10″ and 10′″, respectively, allows the integration of antenna configurations with arbitrary attachment options. In particular with other FOWLP configurations, this is not the case. Further, here in particular illustrated in the context ofFIGS. 2c and 2d , the above discussed structures allow an integrated solution for thermal management. - The fields of application are manifold. The
platform - The same can also be used to develop wireless sensor systems that can be used for any applications in all frequency ranges of the electromagnetic spectrum.
- Further, the platform and the module 10-10′″, respectively, can be used to develop radar systems which can be used for any applications in all frequency ranges of the electromagnetic spectrum.
- As already mentioned above, the integrated antenna can be configured as antenna array or can include an antenna array, e.g., with a plurality of antennas (>5 or even >1000). Here, the several antennas are arranged beside one another such that no or only a minimum overlap with further elements, such as the chips, occurs.
- While this invention has been described in terms of several advantageous embodiments, there are alterations, permutations, and equivalents which fall within the scope of this invention. It should also be noted that there are many alternative ways of implementing the methods and compositions of the present invention. It is therefore intended that the following appended claims be interpreted as including all such alterations, permutations, and equivalents as fall within the true spirit and scope of the present invention.
